Calculate the moment of inertia of the following figure about the axis O. A is a uniform solid cylinder with mass M and radius R. B is a uniform thin rod with mass M and length 3R. A and B objects are attached together and rotate together about axis O. The distance X is and Y is in the figure. The light blue line is going through the center of the cylinder and the point “CM” represents the center of mass of...
The moment of inertia of the human body about an axis through its center of mass is important in the application of biomechanics to sports such as diving and gymnastics. We can measure the body's moment of inertia in a particular position while a person remains in that position on a horizontal turntable, with the bodys center of mass on the turntable's rotational axis. The turntable with the person on it is then accelerated from rest by a torque that...
Two disks are rotating about the same axis. Disk A has a moment of inertia of 4.45 kg.m2 and an angular velocity of +4.87 rad/s. Disk B is rotating with an angular velocity of -7.28 rad/s. The two disks are then linked together without the orques, so that they rotate as a single unit with an angular velocity of -3.59 rad/s. The axis of rotation for this unit is the same as that for the separate disks. What is the...
1) The parallel axis theorem provides a useful way to calculate the moment of inertia I about an arbitrary axis. The theorem states that I = Icm + Mh2, where Icm is the moment of inertia of the object relative to an axis that passes through the center of mass and is parallel to the axis of interest, M is the total mass of the object, and h is the perpendicular distance between the two axes. Use this theorem and...
Two disks are rotating about the same axis. Disk A has a moment of inertia of 9.20 kg·m2 and an angular velocity of +9.96 rad/s. Disk B is rotating with an angular velocity of -8.43 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -3.59 rad/s. The axis of rotation for this unit is the same as that for the separate...
Two disks are rotating about the same axis. Disk A has a moment of inertia of 3.3 kg · m2 and an angular velocity of +7.4 rad/s. Disk B is rotating with an angular velocity of -9.3 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -2.5 rad/s. The axis of rotation for this unit is the same as that for...
Two disks are rotating about the same axis. Disk A has a moment of inertia of 4.50 kg·m2 and an angular velocity of +1.17 rad/s. Disk B is rotating with an angular velocity of -6.93 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -3.80 rad/s. The axis of rotation for this unit is the same as that for the separate...
Which of the following statements is false? The moment of inertia of an object depends on the location of its axis of rotation The moment of inertia of an object depends on the angular acceleration of the object as it rotates An object can continue to rotate in the absence of torque An applied net torque may reduce the angular speed of an object Of the particles that make up an object, the particle with the smallest mass may contribute...
